Description

Method and apparatus for transmitting control information and Method and apparatus for receiving control information

This application claims priority to Chinese Patent Application No. 201611264483.1 entitled “CONTROL INFORMATION SENDING METHOD AND APPARATUS, AND CONTROL INFORMATION RECEIVING METHOD AND APPARATUS” filed on December 30, 2016 with the Chinese Patent Office. All of which are incorporated herein by reference.

The present invention relates to the field of communications, and more particularly, to a method and apparatus for transmitting control information, and a method and apparatus for transmitting control information.

As communication technology advances, as the peak data rate continues to increase, the size of the transport block (TB) (eg, the amount of bits included) also increases.

A feedback mechanism is proposed to improve the accuracy and reliability of the communication. Specifically, the receiving end generates feedback information specific to TB, for example, acknowledgment (ACK) information or negative acknowledgment (NACK) information, based on the received TB decoding structure.

However, if an error occurs in this TB-based feedback mechanism, retransmission of the entire TB will occur and consequently resources will be wasted.

In consideration of this, the TB may be divided into a plurality of code blocks (CBs), and feedback is performed based on the CBs. That is, since the feedback information is specific to the CB, it is possible to prevent the entire TB from being retransmitted due to a transmission error of some data.

However, in such a CB based feedback mechanism, for example, when TB is very large, feedback information specific to a plurality of CBs is transmitted in one feedback process, so that resource overhead of the feedback information becomes relatively large.

To solve this problem, CBs can be grouped into a plurality of CB groups, and feedback is performed based on the CB group. That is, the feedback information is specific to the CB group.

However, in order to implement a CB group based feedback mechanism, control information such as, for example, downlink control information (DCI) needs to include control information of each CB group. Because the size of the TB varies, the amount of CB groups contained in the TB may vary. As a result, the amount of bits in the DCI can vary dynamically, increasing the blind detection complexity of the terminal device, increasing the processing burden of the terminal device, and affecting the user experience.

Embodiments of the present application provide a method and apparatus for transmitting control information and a method and apparatus for receiving control information, thereby maintaining a constant bit amount of the control information, thereby reducing the blind detection complexity of the terminal device and processing burden on the terminal device. To reduce the user's experience.

In this embodiment of the present application, each TB (including TB #A) transmitted in the communication system may be divided into a plurality of (one or more) CB groups, and each CB group includes one or more CBs.

In this embodiment of the present application, the N value corresponds to the maximum amount of CB groups in which TB can be divided.

Specifically, in this embodiment of the present application, for a terminal device (eg, terminal device #A), the maximum amount (ie, N) of CB groups in which each TB can be divided is clear. For example, TB #A transmitted or received by the terminal device #A may be divided into up to N CB groups. For ease of understanding and differentiation, below the maximum value of the N CB groups that TB #A can be divided into is referred to as "N theoretical CB groups."

In this embodiment of the present application, the N value may be determined by the network device.

For example, the network device may determine the N value based on information such as a transmission capability and a processing capability of the terminal device, and a service type or delay requirement of a service to which TB #A belongs.

As another example, the terminal device may alternatively alternatively set the expected value of N based on the above-described information, such as the transmission capability and processing capability of the terminal device, and the service type or delay requirement of the service to which TB #A belongs. The terminal device can transmit the expected value of N to the network device; The network device may determine the N value based on the expected value of N.

Thereafter, the network device can transmit the N value to the terminal device. For example, the network device may use, for example, one piece of indication information (ie, one piece of first indication information) for the N value by using RRC (Radio Resource Control) signaling or physical layer signaling. Ex) can be transmitted to the terminal device.

In this case, the N value may be different for different terminal devices. In other words, the network device may determine different N values for different terminal devices.

Alternatively, in this embodiment of the present application, the N value may be specified by a communication system or communication protocol.

In this case, all N values used by all terminal devices of the communication system may be the same.

In addition, the N value may be stored in the network device, and the network device sends the indication information on the N value to all the terminal devices of the communication system including the terminal device #A using a broadcast message or the like. I can send it.

Alternatively, the N value may be preset in the terminal device #A by the manufacturer, the carrier or the user.

Accordingly, the network device and the terminal device #A may determine the N value.

It should be noted that the methods and processes for determining the above-described N values are merely illustrative for the purpose of explanation. The present application is not limited thereto. If the N value determined by the network device and the terminal device is the same, all other methods and processes for determining the N value by the network device and the terminal device are within the protection scope of the present application.

Returning to step S210, as described above, the control information #A includes N control information fields, and the N control information fields include N theoretical CB groups (i.e., up to N pieces included in TB #A). CB group) one-to-one correspondence.

In addition, the control information field i of the N control information fields may be used to indicate whether the theoretical CB group corresponding to the control information field i is transmitted by the network device or received by the terminal device.

Alternatively, the control information field i of the N control information fields may be used to indicate whether the theoretical CB group corresponding to the control information field i is received by the network device or transmitted by the terminal device.

In addition, in this embodiment of the present application, TB #A may be divided in any manner. If n actual CB groups can be determined, this is not particularly limited to this application.

It should be understood that the above-listed method of dividing TB # A into n CB groups by the network device and the terminal device is merely an example for description and does not particularly limit the present application. The network device and the terminal device may partition TB #A in any manner.

That is, in this embodiment of the present application, n control information fields in the N control information fields (denoted as "n control information field # 1" below for easy understanding and explanation) are corresponding CB groups. (That is, n actual CB groups) need to be transmitted (by a network device or a terminal device). In addition, Nn control information fields in the N control information fields (denoted as "Nn control information field # 2" below for ease of understanding and explanation) are assigned to corresponding CB groups (i.e., N theoretical CB groups). CB group), which is within and different from the n actual CB groups, does not need to be transmitted (by the network device or the terminal device). In other words, the N-n control information fields # 2 indicate that corresponding CB groups do not exist or correspond to CB groups that are not divided.

Therefore, the network device can determine N control information fields (specifically, information carried in the N control information fields) of the control information #A.

In this embodiment of the present application, it should be noted that in the N control information fields, the position of the control information field corresponding to each n actual CB groups may be randomly determined by the network device. This is not particularly limited in the present application.

For example, n control information fields corresponding to n actual CB groups may be continuously arranged in N control information fields.

Alternatively, n control information fields corresponding to n actual CB groups may be arranged at intervals in the N control information fields. In other words, one control information field or control information corresponding to one or more CB groups that do not need to be transmitted (by the network device or the terminal device) between control information fields corresponding to two actual CB groups adjacent in the order of deployment. Fields may be present.

As described above, in this embodiment of the present application, n control information fields of the N control information fields (that is, control information fields corresponding to n actual CB groups) may correspond to a corresponding CB group (a network device or By the terminal device).

In this embodiment of the present application, as a non-limiting example, each control information field may include one bit.

By way of example, and not by way of limitation, the information carried in the n control information fields (i.e., control information field # 1) may be 1, and the control information fields (i.e., control) different from the n control information fields of the N control information fields. Information carried in information field # 2 may be zero.

Whether it is transmitted (by network device or terminal device #A).

For example, when the information carried in the control information field (indicated by the control information field #a for convenience of explanation and explanation) is 1, the terminal device #A may have a CB group corresponding to the control information field #a. It can be determined to be transmitted (by the network device or the terminal device #A).

As another example, when the information carried in the control information field (indicated by the control information field #a for convenience of explanation and explanation) is 0, the terminal device #A may have a CB group corresponding to the control information field #a. It may be determined that it does not need to be transmitted (by the network device or the terminal device #A).

It should be noted that the specific values listed above of the information carried in the control information field are merely illustrative for illustration. The present application is not limited thereto. All other values (or bit sequences) that can be used by the terminal device to distinguish between the CB group that is transmitted and the CB group that do not need to be transmitted are within the protection scope of the present application.

As a non-limiting example, in this embodiment of the present application, in addition to being used to indicate whether a CB group corresponding to the control information field i is transmitted, the control information field i is a CB corresponding to the control information field i. The group may further indicate whether the group corresponds to initial transmission data (or new transmission data) or retransmission data.

As a non-limiting example, in this case, the control information field i may include two or more bits. In the following, Table 1 lists the information that can be carried in the control information field i and the meaning indicated by that information.

It should be understood that the specific values listed above of the information carried in the control information field are merely illustrative for illustration. This embodiment of the present application is not limited thereto. Any other that can be used by the terminal device to distinguish between the CB group that is transmitted and the CB group that does not need to be transmitted, and that can be used by the terminal device to distinguish whether the CB group corresponds to initial transmission data or retransmission data. The value (or bit sequence) is within the protection scope of the present application.

As a non-limiting example, in this embodiment of the present application, in addition to being used to indicate whether a CB group corresponding to the control information field i is transmitted, the control information field i is a CB corresponding to the control information field i. RV of the group may be further indicated.

As a non-limiting example, in this case, the control information field i may include two or more bits. In the following, Table 2 lists the information that can be carried in the control information field i and the meaning indicated by that information.

It should be understood that the specific values listed above of the information carried in the control information field are merely illustrative for illustration. This embodiment of the present application is not limited thereto.

Corresponding control information field) indicates that the corresponding CB group needs to be transmitted (by the network device or the terminal device), and the Nn control information fields in the N control information fields indicate that the corresponding CB group is ( Learning by the network device or the terminal device), that is, the Nn control information fields in the N control information fields indicate that there is no corresponding CB group. It should be noted that it may be. In order to avoid repetition, descriptions of identical or similar cases will be omitted below.

It further includes an NDI field used to indicate whether or not.

As a non-limiting example, for example, when N = 4, the N control information fields may include 4 bits in total.

For example, '0' indicates that the current CB group is not transmitted, and '1' indicates that the current CB group is transmitted. If N control transmission fields are '1100', the NDI indicates TB #A. If the data indicates that the data is newly transmitted, the N control information fields indicate that TB #A is CB group 1 (ie, the CB group corresponding to the first control information field of the N control information fields) and CB group 2 ( That is, CB group 3 (that is, CB group corresponding to the third control information field of the N control information fields) and CB group 4 including only the CB group corresponding to the second control information field of the N control information fields (Ie, a CB group corresponding to the fourth control information field of the N control information fields).

In addition, in the format of control information #A shown in FIG. 5, each control information field may be further used to indicate an RV version of a corresponding CB group.

As another example, FIG. 6 shows another example of a format for control information #A.
